Novel Schiff base ligands derived from ss-amino alcohols with two stereogenic centers were prepared and. used in the preparation of optically pure sulfoxides by using aqueous hydrogen peroxide as the oxidant. A variety of sulfides were smoothly converted into the corresponding sulfoxides cata-lyzed by the chiral vanadium-Schiff base complex. Good yields (>80%) with excellent: enantioselectivities (>99%ee) were obtained in most cases.
